Probably they'd never know, but we should mention that any 0W-30 oil does not meet the GM specs (5W-30 only) for a C6, so there is the small possibility they could deny a warranty claim on your engine.

As for oil freeing up available horsepower, I did read that at one time, Formula 1 cars used a lower viscosity oil to qualify. However, aren't 5W20s used in a lot of new (non performance) vehicles to maximize fuel economy?

Yes, they have to prove that your non-approved oil caused the problem. Trouble is, they have the lawyers and engineers on staff to do the testimony, you have to hire your own lawyer and expert witnesses. You could easily spend as much money as a new engine. Maybe you win, maybe you lose.
BTW, Blackstone labs told me that they often get oil samples from car companies, presumably from warranty claims where the maker thinks the owner did something bad. Usually, just failing to change the oil. But not always.
Me, I figure my C6 will run longer on Mobil-1 5W-30 than I'll want to own it. So I will run the approved oil while under warranty, think about switching after that.

Owners Manual for my 2006 says 5W-30 only, 0W-30 is not approved.

I really doubt that GM would test the oil and try to prove that you didn't have an approved oil. Especially if it was a name brand synthetic like the German Castrol. The great thing about the Internet is that local dealers and large companies like GM tend to avoid situations like denying warranty because of the bad press they will get on the net.

"CSIXS:
Thanx for posting your data. Too bad it made you a target for the more sedentary crowd that sometimes hangs out here.
Keep on tuning - it is nice to see your kind of power numbers without forced induction or nitrous oxide."
